Abstract (en)
The present invention relates to a security device (10) and a system and method based on light detection for detecting the unauthorized opening of containers (computer cases, luggage, filing cabinets, shipping containers, etc.). The security device (10) is mounted inside the container for signalling whether the aperture is opened and includes the following: a power source (12) such as a battery that is independent of any power supply in the container; a light sensor (14) (such as a photo transistor) to detect light entering the container; a controller (18) powered by the power source (12) and connected to the light sensor (14); a warning system (16) (such as an audible alarm system) activated by the controller (18), the controller activating the warning system when the light sensor (14) detects light that exceeds a first predetermined threshold indicating that the container has been breached; and a locking mechanism (128) (key lock, combination lock, infra-red based lock) for enabling and disabling the security device. <IMAGE>
